pawn Код:

ShowPlayerDialog(playerid, DIALOG_BRW, DIALOG_STYLE_LIST, "FD Truck Menu", "Chainsaw \n Shovel \n Fire Extinguisher \n Ladder \n Fire Suite \n Medic Suite \n First AID kit", "Select", "Cancel"); 
//The Dialog does not know what ID it is.

Use this instead

ShowPlayerDialog(playerid, 112911, DIALOG_STYLE_LIST, "FD Truck Menu", "Chainsaw \n Shovel \n Fire Extinguisher \n Ladder \n Fire Suite \n Medic Suite \n First AID kit", "Select", "Cancel"); 
//Shows the ID

Also I would just keep it as numbers, since it is much easier to find if you wish to edit it later
